I just realized I sent this directly to Clemens, instead of to the list.
I guess it's no big deal, but it was supposed to go to the list.

Thanks, Clemens. That explains why I thought I had it working, and
then not working later. The first time, I used the ps command from
http://subversion.ffado.org/wiki/IrqPriorities (even though I'm not
using ffado), which included the -L option (which also shows threads
like H), but the next time I was doing it from memory, and I neglected
to include the -L option, so it looked like it wasn't working when it
really was. Well, one advantage to making that mistake is that I've now
learned something more about ps. I was wondering why there were so few
lines in the output from what I remembered from the first time, and now
I know.

It looks like set_rlimits is working until I look at the realtime priority
with ps. What am I doing wrong?
Realtime priorities are shown by ps only for threads that actually are
using a realtime scheduling policy, and jackd's first thread doesn't.
Use H to show threads.
